I am going absolutely out of my mind trying to solve this issue. I have both a yahoo and gmail account saved on my Rhyme. Both are Synced up. I updated both of those passwords, but I am unable to update them in my phone! When I try to do so within the 'mail' application (the basic factory installed one) it just won't LET me. If I go to settings, account settings and then choose 'update password' and put in the new one and click "Finish Setup" I get a "401 Unauthorized" message! If I choose "Delete Account" I get the same thing! If I go into the phone settings under 'accounts & sync' and attempt to completely delete either account from there I get "This account is required by some applications. You can only remove it by resetting the phone to factory defaults." What in the hell am I supposed to do?!?!
